Histories

Meanwhile, the other rivers are swollen to high flood by the quantity of water that falls into them from the sky, because the country is rained on and cut into gullies; but in the summer they are low, lacking the rain and being drawn up too by the sun.

But the Nahr an- Nil [31.1,30.166] (river), AfricaNile, being fed by no rain, and being the only river drawn up by the sun in winter, at this time falls far short of the height that it had in summer; which is but natural; for in summer all other waters too and not it alone are attracted to the sun, but in the winter it alone is afflicted.
